[0002] Resin grinding wheels are grinding wheels made of resin. They have high strength and are used in cutting discs, double-end grinding wheels, heavy-duty grinding wheels, polishing wheels, etc. They are widely used for rough grinding, rough grinding, cutting and free grinding, such as grinding steel ingots and deburring castings.

[0003] Currently, resin grinding wheels are manufactured by molding the grinding wheel body and mounting ring as a single piece. However, if the grinding wheel body malfunctions and cannot function properly during subsequent use, the mounting ring on the grinding wheel body must also be replaced when replacing the grinding wheel body. This results in high production and usage costs for resin grinding wheels, ultimately leading to poor practical performance. Utility Model Content

[0028] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0029] Example 1: Please refer to Figures 1 to 6 A high tensile strength resin grinding wheel includes a grinding wheel body 1 and several heat dissipation holes 2 and heat dissipation grooves 3 on one side of the grinding wheel body 1. During the production of the resin grinding wheel, by adding reinforcing materials such as glass fiber and carbon fiber, or by optimizing the resin formula and production process, the grinding wheel has high tensile strength, can withstand greater grinding force and impact force, is not easy to break, and improves the safety and reliability of use. When using the resin grinding wheel, heat is discharged through the heat dissipation holes 2 and heat dissipation grooves 3 to prevent its surface from being heated and forming high temperature, which would reduce its service life. For details, refer to Chinese Patent Publication No. CN222327881U. Therefore, the heat dissipation holes 2 and heat dissipation grooves 3 are known technologies and this application has not improved them. Therefore, they will not be described in detail here. Four locking blocks 4 are provided on one side of the grinding wheel body 1. A first screw 5 is connected to one side of the locking block 4. The outside of the first screw 5 is threadedly connected to the inside of the grinding wheel body 1.

[0030] A slot 6 is provided on one side of the locking block 4, and two limiting slots 7 are provided on the side of the slot 6. A locking block 8 is slidably connected inside the locking block 4, and limiting blocks 9 are connected on both sides of the locking block 8. The outside of the limiting blocks 9 is connected to the limiting slots 7. When using a resin grinding wheel, the operator first installs the locking block 4 on one side of the grinding wheel body 1. Specifically, the operator rotates the locking block 4 so that the locking block 4 drives the first screw 5 to rotate inside the grinding wheel body 1 and make a threaded connection with the grinding wheel body 1. This is how the locking block 4 is installed first.

[0031] Then, the personnel align the slot 11 of the mounting ring 10 with the four locking blocks 4 and insert them. At this time, the mounting ring 10 is connected and fixed together with the grinding wheel body 1. Then, the personnel use tools to rotate the second screw 16, so that the adjusting ear 14 drives the insertion block 13 to move downward.

[0032] It should be noted that when the insert block 13 moves downward, because the insert block 13 and the inclined surface of the locking block 8 abut against each other, the locking block 8 will move outward as the insert block 13 descends, and then the locking block 8 will move and insert into the locking groove 17 on the side of the mounting ring 10.

[0033] At this time, while the mounting ring 10 is inserted into the slot 11 and the locking block 4, the locking block 8 and the locking groove 17 are engaged to prevent the mounting ring 10 from rotating or moving, thereby making the mounting ring 10 firmly connected and fixed to the grinding wheel body 1.

[0034] At the same time, the mounting ring 10 and the grinding wheel body 1 can be disassembled and separated by reversing the operation. Of course, after the insert block 13 is raised, the locking block 8 needs to be manually pressed into the locking block 4, and then the mounting ring 10 and the locking block 4 can be separated.

[0035] It should be further added that the locking block 8 is limited by the cooperation of the limiting block 9 and the limiting groove 7 to prevent the locking block 8 from moving excessively.

[0036] A mounting ring 10 is provided on one side of the grinding wheel body 1. A slot 11 is provided on one side of the mounting ring 10. The slot 11 is inserted into the slot 4. An adjustment groove 12 is provided inside the mounting ring 10. An insert block 13 is provided inside the mounting ring 10.

[0037] Both the insert block 13 and the locking block 8 have a beveled side, and the beveled sides of the insert block 13 and the locking block 8 abut against each other. Adjusting ears 14 are connected to both sides of the insert block 13. The adjusting ears 14 are located inside the adjusting groove 12. When the adjusting ears 14 are in motion, they will move inside the adjusting groove 12. It should be further noted that the locking block 4 and the locking block 8 are one component, and the mounting ring 10 and the insert block 13 are one component. Therefore, although there seem to be many parts, there are actually only three parts in the whole, namely the grinding wheel body 1, the locking block 4, and the mounting ring 10. Therefore, it is very quick and convenient to disassemble and replace the grinding wheel body 1 of the resin grinding wheel.

[0038] The adjustment groove 12 is provided with a slide rod 15 inside, and a second screw 16 is connected inside the adjustment groove 12. The outside of the second screw 16 is threadedly connected to one of the adjustment ears 14, and the outside of the slide rod 15 is slidably connected to the other adjustment ear 14.

[0039] The mounting ring 10 has four locking grooves 17 on its side, and the locking block 8 is inserted into the locking grooves 17 when locked.

[0040] Example 2: Please refer to Figures 7 to 9 Each of the four card blocks 4 has a circular groove 18 on one side, and a guide groove 19 is provided on one side of the circular groove 18. Embodiment 2 is suitable for some production precision requirements and needs to further reduce production costs, because Embodiment 2 is cheaper than Embodiment 1. However, the connection and fixing strength between the mounting ring 10 and the grinding wheel body 1 in Embodiment 2 is not as good as that in Embodiment 1, but it can still meet some production precision requirements.

[0041] A spring 20 is provided inside the circular groove 18, and a locking rod 21 is connected inside the circular groove 18. The locking rod 21 is located on one side of the spring 20, and a limit ring 22 is connected to the outside of the locking rod 21. When using the resin grinding wheel, the operator inserts the locking groove 11 of the mounting ring 10 into the locking block 4. At the same time, during the insertion process, the inclined groove 24 of the mounting ring 10 contacts one end of the locking rod 21. At this time, the inclined groove 24 will squeeze the locking rod 21, causing the locking rod 21 to move in the circular groove 18 and squeeze the spring 20.

[0042] As the mounting ring 10 continues to move and insert, one end of the locking block 21 will reach the slot 25 on the side of the mounting ring 10. At this time, the spring 20 will push the locking rod 21 to move and insert into the slot 25 due to the force of the spring resisting the compression, so as to further lock and limit the mounting ring 10.

[0043] It is important to note that the end of the locking rod 21 that contacts the inclined groove 24 is spherical. This allows the locking block 21 to move as the inclined groove 24 moves. Also, when disassembling the mounting ring 10 from the grinding wheel body 1, personnel need to manually push the locking rod 21 back and then separate the mounting ring 10.

[0044] Therefore, in the above process, the card block 4 is inserted into the slot 11 of the mounting ring 10 for initial connection and fixation. Then, the card rod 21 is inserted into the slot 25 on the side of the mounting ring 10 for further limiting connection and fixation, ensuring that the mounting ring 10 and the grinding wheel body 1 are firmly installed together.

[0045] A guide block 23 is connected to one side of the limiting ring 22, and the outside of the guide block 23 is slidably connected to the guide groove 19.

[0046] The mounting ring 10 has four oblique grooves 24 on one side and four slots 25 on the side, and the outside of the locking rod 21 is inserted into the slots 25.

[0047] When using this utility model:

[0048] First, in Example 1, when using a resin grinding wheel, the operator first installs the locking block 4 on one side of the grinding wheel body 1. Specifically, the operator rotates the locking block 4 so that the locking block 4 drives the first screw 5 to rotate inside the grinding wheel body 1 and connects it with the grinding wheel body 1 by thread. This is how the locking block 4 is installed. Then, the operator aligns the slot 11 of the mounting ring 10 with the four locking blocks 4 and inserts them. At this time, the mounting ring 10 is connected and fixed together with the grinding wheel body 1. Then, the operator uses a tool to rotate the second screw 16 so that the adjusting ear 14 drives the insert block 13 to move downward.

[0049] Secondly, when the insert block 13 moves downward, because the inclined surface of the insert block 13 and the locking block 8 abuts, the locking block 8 will move outward as the insert block 13 descends. Then the locking block 8 will move and insert into the locking groove 17 on the side of the mounting ring 10. While the slot 11 of the mounting ring 10 is inserted into the slot 4, the locking block 8 and the locking groove 17 are also used to make the mounting ring 10 unable to rotate or move, thereby making the mounting ring 10 firmly connected and fixed to the grinding wheel body 1.

[0050] Then, in the second embodiment, when using the resin grinding wheel, the operator inserts the groove 11 of the mounting ring 10 into the locking block 4. At the same time, during the insertion process, the inclined groove 24 of the mounting ring 10 contacts one end of the locking rod 21. At this time, the inclined groove 24 will squeeze the locking rod 21, causing the locking rod 21 to move in the circular groove 18 and squeeze the spring 20.

[0051] Finally, as the mounting ring 10 continues to move and insert, one end of the locking block 21 will reach the slot 25 on the side of the mounting ring 10. At this time, the spring 20 will push the locking rod 21 to move and insert into the slot 25 to further lock and limit the mounting ring 10.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
